FIRE-PLACE HEATER.'

*Ow- The Schedule referred to in these Lettore P'artent and making part f the lame Flg e 1 is a vertical section, and Figure 2 isa plan of id heater sectionally. Similar marks of reference denote the same parts.

.This invention relates to that class of heaters that are set'in a chamber formedhy the fire-place, and from which the heatedfair 'can be 'takgto 'an apartment above, or else allowed tc escape into the room itself. My invention relates tc Aa double top to the lire- V chamber, to form cheating-surface, and regulate the eseapeoi? the products, of combustion; also', in ar ranging .the base so as to vintroduce evaporating-vesf sels.

Thebaseof the heater-'is 'formed with an ash-pit, a,- below gthe tcp plate b, vande is th grate.

d isacylinder rising from the plate b. I prefer' to have thisA cylinder d o f sheet-iron, with suitable doors and mica windows. I At the top of the cylinder d is my double tcp, forming-ra radiator and draught-regulator. g

he dome o is made to 't thetop of the' cylinder d, and below this is a second flanged dome, h, leaving a `tine-space', i, that opens at oneside of=the cylinderd,

into .the descending flue g, and in the iiange of the dome h are openings,2, 3', 3, 4, 4,' 5, 5. (See inverted plan of dcme,Figure`3.)

Thev opening 2 is largest,l and is opposite where the products of combustion pass c" to the iiue g, and the holes 3and Laregradually smaller, so that the 'draught land heated products of combustion are thrown forward, toward the front ofthe` heater, to eqnalizethe action of the re, instead of the gases rushing cd' directly to the flue g. f

This construction prevents' the cylinder d and Hue g4 .burning out as rapidly as heretofore, and insures a high heat in the top, e,- which becomes aradiator, to

warm the air that seconds arcundthe heater and Within the case la, and mayv pass by the register or damper l, and an air-pipe, to the rcomabove; or when the regi'ster'is closed, all the heat goes into the room containing this 'fireplace heater. i

l.I provide a hood, s, that extends forward and downward from the, surrounding frame't, and is provided with a register.

This hood aids'in directingr the heat from the appa'f ratus up through the register l and air-tube -m but when that register l is closed, and the register@v open, the heat comes out into the room. y

-. The ue g opens, at the lower end, into .the crossue n', and passes by theascending ue 0tc the chimney.

The base of the heater "is slightly elevated,'so that. f' air circulates around the same, and passes up behind the base, between that and thelcasing k, (seelig. 1;) and in' the'spaces atthe sides of the ash-pt,'1-intrc duce onecr two evaporating-pans, '11, that are `mounted as drawers, and provided with'an openivork end-support, so that the pan can be taken' ont forcleaning or llin Thgese evapcrating-pans, it will'be seen in Figure'fi, are located where a current of air passes over them, and J they are kept warm. These prevent the air becoming vitiated, as heretofore usual with this kind of heater.

' What I claim, 4and desire tc secure by Iietters Plat-l ent, is-

1.- The double dome'e li, forming the top of the cylinder d, and also a iiue, that regulates the escape of the products of combustion, substantially as set forth.

- 2. The evaporating-pan, introduced into the airspace at the side cf the ash-pan, and'belcw the base,

-b, asand for the purposes specified.

3. The hood s, extending from the front f the trame, and provided with the register n, n combination with the heatercylinder d, and. register l, as and for theV purposes specified. t

In witness whereof, I have hereuntoset my signature.
